The Alu alloy flux contains adsorptive and fusible compounds, which can strongly absorb and melt oxides and aluminum slag. These foreign matters are adsorbed on the bubbles and brought to the surface of liquid aluminum with the rising of bubbles. In this way, the liquid aluminum will be purified by degassing and slag removal. Dubai […]

The Molten Aluminum Refining Fluxes are white powder or particle. It is made of a variety of inorganic salts dried and mixed in a certain proportion. It is mainly used to remove hydrogen and floating oxide slag in aluminum solution. Refining agent used in the smelting of aluminum alloy must meet the following conditions: 1. […]

As the third-generation filter equipment, ceramic foam filters for molten metal filtration are particularly widely used in metal smelting and casting production. Foam ceramic filters are used in the filtration and purification of molten metal, which has also promoted the rapid development of the domestic metal casting industry, and improved the yield, machining performance and […]

Regarding foam ceramic filter products, the development began in the 1970s. After more than 30 years of rapid development, the materials of the products are silicon carbide, zirconia, alumina, graphite, etc.; application areas include casting Steel, cast iron, cast aluminum, cast copper filtration. The ceramic foam filter can greatly improve the surface quality and performance […]

Foam ceramic filter is widely used as the aluminum rod casting filter for many years. The high-performance ceramic foam filter board uses alumina as the main raw material, adds auxiliary ingredients according to the optimized design composition formula, and adopts the organic foam precursor impregnation method, which is mainly used for filtration and purification of […]

The ceramic foamed filter provides a high-efficiency filter for the production of aluminum castings, and is widely used in the production of semi-continuous ingots and molded castings. Because of the low melting temperature of aluminum alloy, the high-temperature performance of foam ceramic filter material is not high, alumina foam ceramic filter can be used. This […]

The foam ceramic filter size should be selected according to the nature of the molten metal to be filtered. To filter viscous, thick, poor fluidity, and larger impurity particles, a filter with a larger pore size should be selected. The general principle for the selection of the Foam Ceramic Filter Size: The pore size of […]

The 20ppi ceramic foam filters remove most of the inclusions in the melt, making the overall level of tensile strength closer to stable, and avoiding individual coarse inclusions that sharply reduce the tensile strength. However, most of the smaller inclusions cannot be removed, so the overall level of tensile strength cannot be improved. Using a […]

The Ceramic Foam Filter PPI refers to the plastic material used to make the ceramic foam and is found from the average number of pore boundaries encountered per inch. More recently the CFFs are graded into different PPI categories according to air permeability. The type of filtration occurring in a CFF can be divided into […]

Metal Filtering with CFF is a supplement to metal treatment within the furnace, such as fluxing and degassing or inline filtration. Ceramic foam filters offer a simple, reliable, and cost-effective method to remove inclusions. With the demand for high quality aluminium products increasing, filtering with CFF has proved an optimum method for improving metal quality. […]
